Opened: Nov 26, 2025 Severity: 2-Critical
When a VLAN inside the tenant is deleted and the VLAN is un-assigned from F5OS, a service for the tenant could be deleted. Deletion of service will cause an outage on the tenant. Here are the two log messages on F5OS datapath-cp-proxy[11]: priority="Info" msgid=0x5901000000000045 msg="Confd Event Update:" EVENT="DELETE_SERVICE_ID" FROM="CONFD" TENANTNAME="" ATSE=0 SUBMODULE=0. datapath-cp-proxy[11]: priority="Info" msgid=0x5901000000000034 msg="Service Instance Update Success." TENANTNAME="tenant-1" DOSGRP="[2]" SVCGRP="[7]" SVCID=22.
Because the service is removed, all VLANs on that service will be inaccessible for the tenant and cause an outage in the tenant.
-- Deletion of the VLAN inside the tenant. -- Un-assignment of the same VLAN from the F5OS.
If a VLAN is going to be deleted from the tenant, first un-assign the VLAN inside the tenant from F5OS. Then after a 2 second delay, delete the VLAN inside the tenant.
